'Fantastic' start pleases Froome

Chris Froome thanks Team Sky team-mates, including Nicolas Roche, for helping him maintain the overall lead after day four of the Tour de France, despite losing the yellow jersey to Tony Martin of Etixx-Quick-Step.

Martin's manager Patrick Lefevere says it was also a big team-effort from his side that enabled the German to come out of Tuesday's cobbled course from Seraing to Cambrai on top.
